Rectification under section 37 cannot be used to review an appellate order or reappreciate evidence.

Rectification under section 37 is confined to correcting an obvious and patent mistake apparent from the record; it cannot be used to rehear the matter, introduce new facts, or replace an earlier view through reappreciation of evidence. A debatable issue or a fresh conclusion on the same controversy falls outside rectification. On the facts stated, the Tax Board had gone beyond rectification and effectively reviewed its earlier appellate order, making the rectification order impermissible in law and the answer to the legal question adverse to the assessee and in favour of the Revenue.

Issues: Whether the Tax Board could invoke rectification under section 37 to alter its earlier appellate order by reappreciating the material and reaching a different conclusion.

Analysis: Rectification under section 37 is confined to correcting an obvious and patent mistake apparent from the record. It does not permit the authority to rehear the matter, consider new facts, or substitute a fresh view on the same controversy. A debatable issue or a conclusion reached after reappreciation of evidence cannot be treated as a mistake apparent from the record. On the facts, the impugned order showed that the Tax Board had gone beyond rectification and had effectively reviewed its earlier decision.

Conclusion: The rectification order was impermissible in law and the answer to the question of law is against the assessee and in favour of the Revenue.
